Breathe R Ultra Roof Insulation

Breathable Membrane and Reflective Foil Insulation

Breathe R Ultra 1.2m x 20m is a 2 in 1 breathable membrane and reflective foil insulation for pitched roofs.

It replaces a traditional breathable membrane while reflecting up to 95% of radiant energy, helping reduce heat loss and improve roof thermal performance.

Slim Roof Insulation with High Thermal Performance

11mm Slim Construction

At just 11mm thick, Breathe R Ultra delivers a thermal resistance of 0.711m²K/W, equivalent to around 30mm of EPS insulation.

Its slim design helps save valuable roof space and can reduce the need for thicker insulation materials.

Breathable Roof Protection

Helps Reduce Heat Loss

The reflective aluminium layer helps retain heat, while the perforated membrane allows moisture vapour to pass through.

Breathe R Ultra can reduce heat loss by up to 54% compared with a standard breathable membrane.

Quick and Easy Roof Installation

Lightweight and Easy to Handle

Breathe R Ultra is lightweight, flexible and simple to install above pitched roofs, helping save installation time and reduce material thickness.

For higher thermal performance or projects requiring Building Control approval, consider our BDA certified BreatherQuilt Insulation.
